"Casualty history of this vessel is uncertain; HWC lists a vessel "Pearl" built at Oshkosh and used for the Wolf River run until sold in 1861 to Northwest Packet, for use as a Mississippi tow boat until "worn out." The 7/20/1858 edition of the Milwaukee Sentinel also lists a "Pearl" as having struck a snaq in the Wolf at Freemont and sunk, with no loss of life, on 7/19/1858. It seems likely that the two steamers are the same and that the Pearl was raised from her 1858 mishap and later sold. Lytle & Holdcamper also list a "Pearl" built at Oshkosh in 1857 as abandoned in 1879, whereabouts unlisted."
